Unable to create a dataset from a parquet file in S3
## Describe the bug
Trying to create a dataset from a parquet file in S3.

## Steps to reproduce the bug
```python
import s3fs
from datasets import Dataset

s3 = s3fs.S3FileSystem(anon=False)

with s3.open(PATH_LTR_TOY_CLEAN_DATASET, 'rb') as s3file:
    dataset = Dataset.from_parquet(s3file)
```

## Expected results
A new Dataset object

## Actual results

```AttributeError: 'S3File' object has no attribute 'decode'```
```
